Why is it more dangerous if the bottom number of Blood pressure is high?

The bottom number of blood pressure, known as diastolic pressure, represents the pressure in the arteries when the heart rests between beats. A high diastolic number can indicate that the heart is under increased strain during its resting phase, which may lead to conditions such as Heart disease, stroke, and kidney damage. It can also reflect issues like stiffened arteries or increased vascular resistance. Therefore, elevated diastolic pressure can be a significant risk factor for cardiovascular complications.
